Physical & Chemical Properties

Grape Seed Extract is a reddish-brown to brown fine powder at room temperature, with a slight characteristic bitter and astringent odor. It is partially soluble in cold water, easily soluble in warm water, ethanol and methanol, soluble in ethyl acetate, and insoluble in ether and chloroform. It is stable under normal temperature and pressure, sensitive to light and high temperature, and easy to oxidize and discolor when exposed to direct sunlight or high temperature. Its key indicators include OPCs content ≥70%-95%, moisture ≤5.0%, ash ≤5.0%, and heavy metals ≤8ppm. It needs to be stored in a dark and sealed environment to avoid oxidation and moisture absorption.

Key physical and chemical parameters are detailed in the specification table below, meeting the requirements of food grade, cosmetic grade, pharmaceutical grade and dietary supplement grade.

Main Uses

Grape Seed Extract is a natural botanical extract with strong antioxidant activity, widely used in dietary supplements, cosmetics, functional foods and pharmaceutical fields, mainly used as follows:

Dietary Supplements: As an antioxidant raw material, it helps scavenge free radicals, delay aging, whiten skin, protect cardiovascular health, and enhance immunity.
